Abstract
The invention discloses a shedding mechanism of a six-shuttle circuit loom. The shedding mechanism comprises a cam, heald bars, guide rods, upper sliding blocks and lower sliding blocks, wherein a double-groove curved slideway is arranged on the outer circumference of the cam; thirty groups of upper sliding blocks and lower sliding blocks are uniformly arranged on the double-groove curved slideway; three circular holes side by side are formed in each upper sliding block and each lower sliding block; two guide rods penetrate through circular holes in upper edges of the corresponding upper sliding block and the corresponding lower sliding block; the heald bars penetrate through the circular holes in the middles of the upper and lower sliding blocks; the bottoms of the heald bars are fixed on the corresponding lower sliding block through set screws; a rectangular heald frame is fixed at the upper part of each heald bar. The double-groove curved slideway is in a sine curve groove wire form; the lifting distance of the upper and lower sliding block of each group on the double-groove curved slideway is 120mm. According to the shedding mechanism designed by the invention, a large cam structure of the double-groove curved slideway replaces a traditional swing arm type small cam shedding mechanism; by using the structure with the upper and lower sliding blocks and the guide rods, the complexity of equipment is reduced; meanwhile, tension fluctuation of warp yarns can be effectively reduced, and the texture quality is improved.
Description
Technical field
The present invention relates to circular loom field, particularly relate to a kind of six shuttle circular loom shedding mechanisms.
Background technology
Circular loom shedding mechanism need realize carrying out odd-even alternation layering to equally distributed warp thread by ectonexine heald frame.The warp thread uniform along main frame is divided into two-layer up and down with odd even and alternately changes by heald frame, forms 6 shed opens simultaneously, for 6, shuttle is planted 6 weft yarns simultaneously.
Existing circular loom shedding mechanism adopts the little cam shedding mechanism of swing arm mostly.The little cam shedding mechanism of swing arm is on main shaft, be fixedly mounted with little cam, the excircle of little cam is processed with the simple curve boss of periodically rise and fall, this boss lower planes is connected with cam roller Structure deformation, roller is connected with swing arm head movement, be flexibly connected with swing arm seat in the middle part of swing arm, swing arm afterbody is fixedly connected with comprehensive band, and swing arm seat is packed on chassis, thus drives heald rod and heald frame to carry out out combining motion.But the little cam shedding mechanism complex structure of this type swing arm, parts are extremely many, not easily process, assemble and keep in repair, and fault rate is high.
Summary of the invention
The present invention for solving the problem, provide a kind of replace the little cam shedding mechanism of original swing arm with double flute line big cam shedding mechanism mould volume six shuttle circular loom shedding mechanism.
A kind of six shuttle circular loom shedding mechanisms, comprise cam, heald rod, guide post, top shoe and sliding block, cam excircle is placed and is provided with dual-cavity curved surface slideway, the uniform 30 groups of top shoes of dual-cavity curved surface slideway and sliding block, top shoe and sliding block have three circular ports side by side, two guide posts pass the circular port of one group of upper and lower slide block top edge, heald rod is through the circular port in the middle of upper and lower slide block, the bottom of heald rod is fixed on sliding block by holding screw, and the top of heald rod is fixed with rectangular heald frame.
Described dual-cavity curved surface slideway is sine curve line of rabbet joint form.
It is described that often to organize the lifting distance that upper and lower slide block moves on dual-cavity curved surface slideway be 120mm.
Beneficial effect of the present invention: the shedding mechanism of the present invention's design, the big cam structure of its dual-cavity curved surface slideway instead of the little cam shedding machine mechanism of swing arm traditionally, the structure of upper and lower slide block and guide post reduces equipment complexity, effectively can reduce average tension on warp simultaneously, improve fabric quality.
